Merge branch 'icc-shikra' into icc-next

Add Epoch Subsystem (EPSS) L3 scaling support on Qualcomm Shikra SoC.
EPSS hardware on Shikra is similar to other SoCs but supports only twelve
L3 frequency entries (LUT). Reading the LUT beyond supported frequencies
can expose incorrect frequencies.
Introduce new compatible to represent this constrained variant of EPSS.
